If Trump is elected President, he will be the head of the Executive Branch of Government. Most agency heads, he can fire at will. He will have to replace them with Senate confirmations, but he can still fire most of them.
Some, he may not be able to fire. Those he can reassign to a different office location or duty station. I think shipping them off to Fairbanks, Alaska or setting up a desk in Guantanamo, Cuba might be amusing.
The best way to destroy the Deep State is to force them quit, while sending a clear message to those lower down in the organization.
